Favourite icon is significantly more difficult to distinguish between on/off.
When an ability is maxed, it dims the second line which also contains the Basic, Special, Unique, Leader tag, which is arguably more important than the name of the ability itself. I'd take a cue from ships and move the ability level into the icon's lower corner, so it's either a #, an omega, a zeta, or a checkmark (for maxed non-zeta/omega abilities). Then brighten up the ability type tag so it's as visible as the name.
No Find button is bad. Remove the mini-potrait beside the stars and replace with find.
Jumping to the mod screen seems to have a mod initially selected, showing its stats instead of the heroes stats and the Loadout button. I'm guessing this is a bug and not intended.
Mod loadout on main screen is small enough on a phone that it's very difficult to distinguish certain set types, especially if it's purple.
Use of space on a rectangular phone is pretty bad. Lots of empty space with tons of stuff crammed at the edges. Relic and ship button seem like they could fit nicely under each set of 3 gear slots. Instead the relic causes most Legendary and HJ heroes' abilities to scroll.
The ability texts are "problematic" - both the text and corresponding images seems low-res and is harder to read/see. The mods, likewise (lo-res/fuzzy looking)
There seems to be a lot of wasted space around the character - which also seems on odd choice given the small/cramped feel of the rest of the UI.
No "FIND" labels for shards or mod interface for new players is a very bad idea. I'm sure for the rest of us it will be second nature, but not a good design choice.
